+Subject: [PATCH] media: uapi: hevc: Add segment address field
+
+From https://patchwork.linuxtv.org/patch/60725/
+Changes requested, but mainly docs.
+
+If HEVC frame consists of multiple slices, segment address has to be
+known in order to properly decode it.
+
+Add segment address field to slice parameters.
